Abstract

L’invention concerne un dispositif (1) de contrôle de l’angle de braquage d’un véhicule automobile comprenant un contrôleur latéral (14) adapté à générer en sortie une commande vers au moins un actionneur d’un système de direction (15) du véhicule agissant sur l’angle de braquage des roues directrices du véhicule par l’intermédiaire de l’angle de rotation du volant du véhicule, de façon à suivre une trajectoire dans un mode de conduite automatisée, ledit dispositif étant caractérisé en ce qu’il comprend en outre un module (11) d’analyse de suivi de la trajectoire apte à détecter des conditions de route sans pente longitudinale et sans inclinaison latérale et, lorsque de telles conditions de route sont détectées, à fournir en sortie une valeur courante d’erreur d’angle de braquage des roues directrices du véhicule à un module (16) de compensation automatique de décalage d’angle du volant relié audit contrôleur latéral. Figure à publier avec l’abrégé : Fig. 1The invention relates to a device (1) for controlling the steering angle of a motor vehicle comprising a lateral controller (14) adapted to generate as an output a command to at least one actuator of a steering system (15). of the vehicle acting on the steering angle of the steered wheels of the vehicle via the angle of rotation of the steering wheel of the vehicle, so as to follow a path in an automated driving mode, said device being characterized in that it further comprises a module (11) for analyzing the trajectory capable of detecting road conditions without longitudinal slope and without lateral inclination and, when such road conditions are detected, to output a current value d steering angle error of the steered wheels of the vehicle to an automatic steering wheel angle offset compensation module (16) connected to said side controller. Figure to be published with the abstract: Fig. 1
